Howto solve error code 0xA0000400
To resolve this issue, follow these steps:
1. Restart your computer and see if that resolves the problem.
2. Open Command Prompt as Administrator and execute sfc /scannow, then run dism /Online /Cleanup-Image /RestoreHealth.
3. Disable any third-party antivirus software temporarily to ensure it’s not blocking access to Windows Store services.
4. Check the integrity of your system files by running the System File Checker tool again from an elevated Command Prompt window, after restarting.
5. Reset the Microsoft Store application by going to Settings > Apps & features, finding “Store” in the list, and selecting Advanced options where you can choose the Reset button at the bottom.
6. If none of these methods work, create a new user account on your device and test if the error persists there as it might indicate a profile-specific issue rather than a system-wide one.
